There is nothing at all wrong with global warming, per se. The problem comes with the RATE at which global warming is taking place. In previous times, with slow global warming and small populations, it didn't take much for small numbers of people to gradually migrate from places where the environment was becoming unsuitable to places where the environment was getting better. And there were no such things as borders. Today, with higher populations and faster changes in climate, we need to be able move millions of people quickly from one place to another. This is hugely expensive, and not only that, there is huge ethnic resistance to millions of people suddenly migrating from one place to another. Wars have started over less.
